I asked this question over on the Kindle forum and they thought maybe I should ask it here instead, so here goes:

I use Calibre to manage my library, in doing so I change the titles to match my naming convention. In the last few days I have about 62 books that both the Kindle and K4PC are saying are in my archives but are in fact on both the kindle and in the K4PC directory. Is there any way to get Amazon to stop showing these books as being in my archive and recognize that they are on the device?? I should mention these files were not named recently, they have always had their names but suddenly Amazon is saying they are in the archive also, although they are on the device.
